Re: [amsat-bb] OPAL Beacon

[mike.rupprecht@xxxxxxxxxxx (Mike Rupprecht)]

Hi Mineo, 

Beacon 1 send an AX.25 packet frame containing OPAL's current time stamp
and a 2 bit summary of OPAl's health. These 2 bits are defined as : 
00 = all systems working nominal 
01 = voltage to high 
10 = temperature to high 
01 = voltage to low
